Setting Up Desktop and Application Pools in View

If you edit an existing pool or store replicas on a separate datastore, View uses a different sizing formula.
See “Sizing Formulas for Creating Linked Clones When You Edit a Pool or Store Replicas on a Separate
Datastore,” on page 206.

Example of a Storage Sizing Estimate
In this example, the parent virtual machine is configured with 1GB of memory. The parent virtual machine's
disk size is 10GB. A linked-clone pool is created with 10 machines. Persistent disks are configured as
2048MB in size.
The OS disks are configured on a datastore that currently has 184.23GB of available space. The persistent
disks are configured on a different datastore with 28.56GB of available space.
Table 15-3 shows how the sizing formulas calculate estimated storage requirements for the sample linked-
clone desktop pool.

Sizing Formulas for Creating Linked Clones When You Edit a Pool or Store
Replicas on a Separate Datastore
View calculates different sizing formulas when you edit an existing linked-clone desktop pool, or store
replicas on a separate datastore, than when you first create a pool.
If you edit an existing pool and select datastores for the pool, View Composer creates new clones on the
selected datastores. The new clones are anchored to the existing snapshot and use the existing replica disk.
No new replicas are created.
View estimates the sizing requirements of new clones that are added to the desktop pool. View does not
include the existing clones in the calculation.
If you store replicas on a separate datastore, the other selected datastores are dedicated to linked-clone
disks.
In these cases, View does not include space for replicas when it calculates storage recommendations for
linked-clone disks.
Table 15-4 shows the formulas that calculate the estimated sizes of linked-clone disks when you edit a pool
or store replicas on a separate datastore.
